Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.01525 |
| Opus 5.5 | $0.00007 | $0.00610 |
| Sonnet 5.5 | $0.00004 | $0.00305 |
| Haiku 4.5 | $0.00002 | $0.00153 |
Grade A, and why
docs-patterns scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation Writing Patterns
Before writing, read 2-3 existing docs in the same category to match their tone and structure.
Writing Style
Tone: Technical but accessible. Imperative for instructions ("Use X..."), declarative for specifications ("The User model has these fields..."). No marketing language.
Brevity is paramount. A doc that could be 100 lines should not be 300. Every paragraph must earn its place. If a table communicates it better than prose, use a table. If a link to another doc covers it, don't restate it. Be precise, not exhaustive.
Doc Types
Pick the type before the shape -- the four Diataxis types each want a different shape. Two questions place any doc: action (doing) or cognition (understanding)? Study (learning) or work (the task at hand)?
| Type | Purpose | Shape | Which am I writing? |
|---|---|---|---|
| Tutorial | Learning-oriented -- teach a newcomer by doing | Guided, sequential lesson whose steps are guaranteed to work | "Teaching a beginner start-to-finish; if they follow along they succeed." |
| How-to | Task-oriented -- reach one real goal with existing skills | Numbered steps for a single task; assumes competence | "Helping a competent user accomplish one specific goal." |
| Reference | Information-oriented -- authoritative facts consulted mid-task | Austere, structured to mirror the code, consistent patterns and tables | "Describing what is -- consulted, not read through." |
| Explanation | Understanding-oriented -- the why, context, trade-offs | Discursive prose; weighs alternatives and reasoning | "Explaining why -- read away from the code to understand." |
The Section Structure below is the reference shape. Don't force tutorials, how-tos, or explanations into it -- each has its own shape above.
Files with their own rules
Before editing one of these, read its file in this skill's directory; a reviewer reads the matching file under references/.
What ships with it
10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

docs-patterns is a skill published in the GitHub repository Jartan-LLC/grimoire (2 stars, last pushed yesterday), licensed MIT. It adds 18 tokens to every session and 1,525 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
